The accompanying drawing illustrates my invention; Figs. 1 and 2 areV end and side elevations respectively of my glue' spreader showingthe 'parts i'nposition with the platev atrest, 2 'being in partial section; Slis-a fragmental end elevation showing the parts inthe kposition they occupy When the 20 glue-spreading plate is midway of its passage through the glue; and Fig. 4 is aA ragmental sidev elevation illustrating a modied form of mechanism for movingthe glue-spreading plate. i f n Y By invention comprisesa glue pan partially surrounded by a steam jacket 11 which is supportedfrom the floor as bythe legs 12. Extending longitudinally above the center v of the glue pan 10 is a rotatable shaft k13 upon 30 Which are rigidly mounted brackets 14 Which support the glue-spreading plate 15. The shaft 13 is so arranged relative to the glue pan 10 that as the shaft is rotated the plate 15 Will pass through the glue in the pan.

For the purpose of operating the plate 15, I prefer to employ some suitable source of motive power such as the electric motor which is conveniently mountedupon a shelf 21 attached to the legs 12. The motor 20, through 40 gears 22 and 23, drives a Worm shaft 24 upon Which is rigidly mounted a Worm 25. The Worm 25 meshes With a Worm Wheel 2G Which is rigidly attached to shaft 27 rotatablyr mounted in suitable bearings 28 and 29. The

' 45 shaft 27 carries a gear 30 which mesheswith ply theboardsto the glue-covered -face of the- Vmotion: to such shaft/so that the plate wilfljrotate through the gluefin the@ pan 1 0 anilwill remainat rest for an. interval in: asubstantieal lyy horizontal position above the glue. In'

theplate' 15. ila-aV horizontal the. glue. ludus .constructiolllis 1h00 mounted directly on the shaft of the electric motor 2O and meshes with a Worm gear 41 carried by a shaft 42. The shaft 42 is rotatably supported in suitable bearings 43 and 44 and on such shaft there is rigidly mounted a pinion 45 which meshes with an idler gear 46 which is rotatably supported conveniently from the end of the steam jacket 1l. The idler gear 46 meshes with a gear 47 which is rotatably mounted on the shaft 13.

The shaft 13 extends outwardly beyond the gear 47 and supports an axial slidable clutch member 48 which at its inner end is `provided with a conical clutching surface complementary to a clutching surface in the adjacent end face of the gear 47. Theclutch member 48 rotates with the shaft 13 and may be moved back and forth axially thereof by means of a clutch shifter 49 which extends downward across the outer face of the idler gear 46 and is pivotally mounted at its lower end. A spring 51 acts between the clutch ing the period of the engagement of the cam 52 and thecam roller 53 the shaft 13 remains stationary with the `plate 15 in the horizontal position illustrated in Fig. 4; The cam 52 conveniently has an extent of approximately 240 degreesin order that the plate 15 may remain stationary through two-thirds of the revolution of the idler gear 46.` During the remaining one-third of the revolution of the idler gear the shaft 13 makes a complete revov lution to carry the plate15 through the glue in the pan 10.

My invention is not limited to either of the particular meansdescribed for imparting an intermittent motion to the'shaft 13 and plate 15, as the desired result can be accomplished in any convenient manner. In the modification of my inventionillustrated in Figs. 1, 2, and .3,v I have illustrated the worm 25 as l Y mounted Ion an individual shaft, while in the construction shown in Fig. 4 the corresponding worm 40 is mounted directly on the sliaft of the motor 20` I prefer the former method of mounting, as in such a construction the end thrust incident to a worm drive is not imparted to the armature shaft of the motor 'I claimas my invention:

1. A device suitable for use in applying adhesive material to the faces of boards or the like, comprising an open-topped pan for containing VaV supply of the adhesive material, a substantially flat spreader plate pivotally mounted Ona horizontal axis above the level of the adhesive in the pan and adapted to dip into and emerge from the adhesive material as it rotates, and means for moving said plate intermittently about its axis to invert and dip it periodically into the adhesive material in said pan and to come to rest thereabove in a predetermined position such that articles may be applied to and removed from its adhesivecovered surface.

2. A device suitable for use in applying adhesive material to the faces of boards or the like, comprising'an opentopped pan for containing a supply of the adhesive material, a substantially fiat spreader plate pivotally mounted on a horizontal'axis and adapted to dip into and emerge from the adhesive material asit rotates, and means for moving said plate intermittently about its axis to invert and dip it periodically into the adhesive material in said pan and to come to rest'thereabove in a predetermined position such that articles may be applied to and removed from its adhesive-covered surface.

The invention set forth in claim 2 with the addition that said pan has avcylindrical hand at Rushville, Indiana, this 27th day of March, A. D. one thousand nine hundred and twenty-six. HARRY G. FRANCIS.
